Great answers. Because of family health issues over the years, I've had to do a lot of research on the web, and I also used to write separate brochures for patients and brochures for healthcare professionals on the same topics in the olden days of print.
Even if you are a generally well-informed, highly educated person, if you just learned you MIGHT have a particular condition or that you just found out that you do have a serious condition, having access to both levels of information is great. You are able, on the
cancer.gov site, to read the patients only section. Later, when you can handle it, or you realize you'll need to do more research on your own, you'll know exactly where to look for more in-depth information. My main complaint about that page, though, is how those two labels aren't designed in an obvious way. As I took a quick look at the page, I didn't even see the two choices in the nav! Believe me, that sort of thing has to be very clear, especially when someone is in shock, depression, suffering from “chemo brain” (a real condition), etc. I also like how it defaults to the patient view. The site is poorly designed: very unattractive, with too much happening and not enough clear differentiation or whitespace, but I like how they have separated the two views (except for not making it obvious enough).
And, yes to the making info clear and easily skimmed for the healthcare professionals. They also need to quickly determine if this valuable info for them or just the same-old stuff, they are usually in a hurry, yet they still need to be able to grasp the nuances, assess the reliability of the information, etc.
Ginny makes an interesting point about doctors needing to assess whether this is good information to give their patients. My immediate family members have been through many conditions or died from them, including leukemia, lymphoma, breast cancer, brain tumors… well, the list goes on and on. Not one doctor has ever recommended that any of us go on the web for more information. The very thought horrifies them. I can't imagine any of them even vetting a page for this purpose. I wonder if this will change as doctors feel more of a squeeze as the healthcare system changes, or what organizations can do to change this.
